Structural reversed beam positioning and reinforcing device and reinforcing method

The invention discloses a structural reversed beam positioning and reinforcing device and a reinforcing method. The system comprises a structural floor slab and a structural reversed beam connected with the structural floor slab into a whole, beam side formworks are symmetrically arranged on the two sides of the structural reversed beam in a supported mode, L-shaped supports are symmetrically arranged on the beam side formworks on the two sides, each L-shaped support is composed of a horizontal rod and a vertical rod vertically welded to the horizontal rod, a first through hole is formed in each vertical rod, the vertical rods of the L-shaped supports on the two sides penetrate through the first through holes through split bolts and then are fixed to the structural reversed beam, and the horizontal rods make contact with the surface of the structural floor slab. According to the device and method, the side face of the structural reversed beam at the joint of the structural floor slab and the structural reversed beam is fixed through a formwork and a welded steel frame, the problems that the structural reversed beam is inaccurate in positioning and poor in forming effect are solved,meanwhile, loss and waste of materials are reduced, the reinforcing requirement of the structural reverse beam is met, meanwhile the integrity of the structural reversed ridge and the structural floor slab is enhanced, and the construction quality of the structural reversed beam is ensured.
